FluBBA has ported SMSAdvance, the Sega Master System EMU, to run from a Slot-1 linker. The port features a few enhancements such as the ability to run ROMs which are zipped. Please see the change log for more information.

This is really great! I'm playing my old Sega Master System games on my DSi and they look superb. They're all working absolutely perfectly. Just remember to close the menu on the touchscreen after you load a game because the top screen is frozen and won't start the game until the menu is closed.

EDIT: After further screwing around, I found that most of those were just bad ROMs. Once I got good ROMs, they worked. Ace of Aces and Shadow Dancer still won't work after trying many versions from many different places though.

Heh, leave it to me to find games that don't work. I seems to have a knack for that.

EDIT2: Just needed a BIOS file for Ace of Aces and Shadow Dancer. Now, all games I tried (44 in total) now work fine.

Could use some hints as to what are good games (not RPG's please) for SMS.
